Thomas Edison

Thomas Edison used a tinfoil cylinder to make the phonograph in 1877. This early version required hand-cranking to operate and had limited playback capabilities.

Edison's phonograph involved a cylinder covered in a thin sheet of tin foil. Sound was collected by a horn, which caused a diaphragm to vibrate. This was connected to an arm, so when the diaphragm vibrated (because of the sounds) - indents or grooves were made on the foil. This "stored" the sound. In order to playback the sound - the arm went over the grooves, causing the diaphragm to vibrate in the same way it had before. These vibrations reproduced the original sound.

Thomas Edison invented the light bulb to provide a practical and efficient source of artificial light. He invented the phonograph as a way to record and play back sound, with applications in entertainment and communication. Both inventions contributed to significant advancements in technology and changed the way we live.

Color of the material is not important when selecting a material for a light bulb filament. The key properties to consider are electrical conductivity, melting point, and heat resistance.

Yes, Thomas Edison was successful in creating a practical and commercially viable incandescent light bulb. His invention revolutionized the way we light our homes and workplaces, and his work laid the foundation for modern lighting technology.

It's not unusual for a two year old to have a limited vocabulary or be a late talker. Every child develops at their own pace. If you are concerned, consider consulting with a pediatrician or a speech therapist for further guidance and evaluation.

The value of a 1901 Gold Moulded 2 minute black wax record varies depending upon condition, correct box, title, and artist. These records are prone to a fungus mold that destroys the surface. The record ideally should have a shiny black surface without any blemishes. Cracks, chips, scratches, and gouges vastly reduce record value. That is the first hurdle. The title is very important. Tunes that have stood the test of time such as a Souza March will command good prices. That is the second hurdle. The artist is very important. Some people collect specific artists like Vernon Dalhart. You won't find Caruso on Edison records but will find some operatic singers who are very collectible. That is the third hurdle. Lastly, the record box and the lid with a corresponding number to the record adds to the value. All of this being said, a record that is playable is worth from $2 to $300. A rube sketch with a crack in an incorrect box might command $2 while a mint Sophie Tucker in the box with correct lid could bring $300. eBay seems to be the great value finder for records. The ones that are most desirable go for handsome prices while the others hover around $5 to $8. I hope that helps.

Because Thomas Edison was one of the biggest dicks in history. I mean the dude electricuted cats and dogs and even an elephant to try and prove that Nikola Tesla's AC was worse than his DC (Which was wrong AC was sooo much better.) And Edison turned down Tesla's idea of radar (which was invented 17 years after teslas idea of it) when proposed to the US Navy because Edison hated Tesla. Man Edison sucked, I mean what a jerk right?

Nikola Tesla claimed that Thomas Edison stole the idea for the light bulb from him. Tesla accused Edison of unfairly taking credit for his work on developing alternating current systems for electricity.

Thomas Edison invented the phonograph in 1877 to record and play back sound. He wanted to create a device that could both capture and reproduce sound for entertainment and communication purposes. Edison's phonograph paved the way for the development of modern audio recording technology.

Well, first of all, to clarify: Thomas Edison developedthe light bulb, and several other people were working on it at the same time. How Edison changed the world was to make electric lighting practical and inexpensive for everyone. However, had he not been forced (mostly by the work of Westinghouse) to go to alternating current, electric lighting would have never become the success it did. Edison insisted (wrongly) that electric lighting should be DC, not AC.

Nikola Tesla was referred to Edison by a mutual friend. Tesla emigrated to New York and gave a recommendation letter to Edison who hired him to help develop DC power systems. Their partnership did not last long. Instead of working on DC power as Edison challenged him, Tesla chose to improve Faraday's AC power. Edison would not listen to Tesla's arguments for AC power, and Tesla quit. George Westinghouse then bought Tesla's AC patents, and directly challenged Edison in the current wars which Westinhouse eventually won. Ironically, many devices used today are DC (computers, cell phones, LED lights, etc.) as Edison predicted, and converters have to be used to step down from AC back to DC.

Thomas Edison was an American inventor and businessman who contributed to the development of numerous devices, most notably the phonograph, motion picture camera, and the electric light bulb. He held over a thousand patents for his inventions and played a key role in the commercialization of electric power distribution. Edison also founded Edison General Electric, which later merged with another company to become General Electric.

No, Thomas Edison did not blow up a train. He was a renowned American inventor known for his contributions to the development of the light bulb, phonograph, and motion pictures. There is no credible evidence to suggest he was involved in any train explosions.

No, Albert Einstein and Thomas Edison were not related. They were both prominent figures in the fields of science and technology, but they were not family members.

Thomas Edison opened his laboratory in Menlo Park, New Jersey in 1876. It was here that he developed many of his most famous inventions, earning him the nickname "The Wizard of Menlo Park."

Light bulbs will likely continue to improve through advancements in energy efficiency, longer lifespan, increased brightness, and smart technology integration for control and automation. LED technology is expected to dominate future innovations, with focus on reducing energy consumption, enhancing connectivity, and improving overall user experience. Furthermore, efforts to make light bulbs more sustainable through recyclable materials and eco-friendly manufacturing processes will also be a key aspect of future improvements.

The nursery rhyme Thomas Edison heard when he turned the handle of the first phonograph was "Mary Had a Little Lamb." This demonstration showcased the ability of the phonograph to record and play back sound, marking a significant moment in the history of audio technology.

No, the original light bulb that Thomas Edison invented is not still lit today. The filament in the bulb would have burned out a long time ago. However, there are modern versions of light bulbs that are based on Edison's original design.

Thomas Elva Edison Invented Light bulb, so, one can say that he is the father of artificial light. He never invented it for the sake of any public good ,that invention was an accidental event actually . Although, now a days people may say that because it was needed for lightening up the streets and at other things, which takes place during night and which need artificial light, but believe me this is not a case here and every other possible usage for the same was determined afterwards.

The light bulb was first used in homes in the late 19th century, with Thomas Edison's invention of the incandescent light bulb in 1879. It gradually replaced gas and oil lamps as the primary source of indoor lighting.

A 100-watt lamp produces more light because it consumes more electrical power than a 25-watt lamp. The higher power input allows the 100-watt lamp to generate more heat and light, resulting in a brighter glow.

Thomas Edison famously made over 1,000 attempts before successfully inventing the light bulb. His perseverance and dedication ultimately led to one of his most notable inventions.

The light bulb improve the quality of life by, it was easier for people to see around their house. The light bulb used less energy and would last longer. Wouldn't have to use windows orlanterns as your light. You could use it in the dark. More goods are produce.... Meaning workers had to work longer and get better pay. More safe when you are in the dark you could see and know what you are doing, was safer.
